KEENE — The Attorney General's Office is urging people to come forward with information that might help solve what investigators are calling an apparent homicide.

David Wheelock, 48, of 170 Pearl St. was found dead in his home around 9:30 p.m. Saturday.

"We initially had a 911 call that was for medical assistance, but once we got there we found the victim, Mr. Wheelock, was the victim of an apparent homicide ... that he had been shot," Assistant Attorney General Benjamin J. Agati said Sunday.

Anyone traveling on Pearl Street between 9 and 9:30 p.m. Saturday is asked to contact the Keene Police Department. Wheelock's single-family home is near the intersection of Pearl Street and Meadow Road.

According to the state's sex offender registry, Wheelock was convicted of 28 child pornography charges in 2005.

Family members identified Wheelock's body, Agati said. His home at 170 Pearl St. was equipped with a handicapped-accessible ramp.

"His family had owned the home for some time before he took ownership of it," Agati said.

Because of people Wheelock had spoken to on Saturday, investigators know the shooting took place between 9 and 9:30 p.m., Agati said.

"It is not very often that we have a small time frame that we are looking for the public observations and truly this is one of these moments where we are focused on this time frame of 9 to 9:30," Agati said.

Pearl Street is not a main thoroughfare, but it does connect Winchester and West streets. Investigators believe there was a lot of traffic that night, Agati said. Anyone with information is asked to call Keene police at 357-9820.
